Netgear ReadyNAS 4220 User Manual

For detailed information about configuring, managing, and using your ReadyNAS storage 
system, see the ReadyNAS OS 6 Software Manual, which is available at 

NETGEAR maintains a community website that supports ReadyNAS products. Visit

updates, documentation, an active user forum, and much more.

Your ReadyNAS storage system is intended for installation in a restricted access location 
(dedicated equipment rooms, service closets, and the like) only.

Keep the following considerations in mind as you install your system:

Ambient operating temperature. If the system is installed in a closed or multiunit rack 

assembly, the ambient operating temperature of the rack environment might be greater 
than the ambient temperature of the room. Therefore, consider installing the equipment in 
an environment compatible with the maximum rated ambient temperature. See 

Reduced airflow. Mount the equipment into a rack so that the amount of airflow required 
for safe operation is not compromised.

Mechanical loading. Mount the equipment into a rack so that a hazardous condition 
does not arise due to uneven mechanical loading.

Circuit overloading. Consider the equipment’s connection to the power supply circuitry 
and the effect that any possible overloading of circuits might have on overcurrent 
protection and power supply wiring. Consider equipment nameplate ratings when 
addressing this concern.

Reliable grounding. This product requires reliable grounding to be maintained at all 
times. To ensure this, ground the rack itself. Pay particular attention to power supply 
connections other than the direct connections to the branch circuit (for example, the use 
of power strips).

Clearance. Leave enough clearance in front of the rack (about 25 inches) to enable you 
to open the front door completely and in the back of the rack (about 30 inches) to allow for 
sufficient airflow and ease in servicing.
